Potential interplay of resistance genes between enteric bacteria

Szmolka et al (2021) Front Microbiol 17 March, 2021

Commensal and pathogenic strains of multidrug-resistant (MDR) Escherichia coli and non-typhoid strains of Salmonella represent a growing foodborne threat from foods of poultry origin. MDR strains of Salmonella Infantis and E. coli are frequently isolated from broiler chicks and the simultaneous presence of these two enteric bacterial species would potentially allow the exchange of mobile resistance determinants.
A recent study in Front Microbiol found that commensal E. coli could be potential reservoirs of resistance for S. Infantis.
IncI1 plasmids could make the greatest contribution to the microevolution and genetic interaction between E. coli and S. Infantis.
